I .will describe'the invention as applied to a rotary knitting machine of the needle machine having .a-latch ring functionngas: usual in such-typeof machine, but it Js'tobe understood that in applying the invention to a spring needle machine of the circular type, I use a ringor partial ring instead of a latch ring, but similarly supported and adapted to be tilted out of functioning position, such ring or partial rin'g carryi'ng the parts of the cutterjherein disclosed as carried byv the latch ring. In the spe'cification and claimsthe term" support is employed in a generic sense'as including both a latch ringcooperatingwith latch needles andaring or partial ;ri1 1g at or above the circle of, spring heardjneedles e Referr ng more part cularly to the-draw- 1ngs,tl ie fram1ng ofthe machmeis indicated at 1. It isprovided with atable 2 upon which is uitably supported the needle cylinder 8 and adjacent theretojare the usualiknitting other cams for controlling the. positions of; the needles during both rotary and reciprocating work,since in thepresent disclosure means are provided for knitting a stocking With heel and toe {pockets the "needles being manipulated during the knitting 10f such pockets narrowing and :Widening. pickers in a we'llknow n manner, not herein necessary to set forthin detail." Y

Suitably mountedin the v framing, is the niaindrive shaft 4 thereon theusual pulleys indicated at and alsohavifng fast thereon a; cam 6, thei'function of which will be hereinafter Qset forth. QAlso mounted. in

theirafniin isftheusual cam shaft 7 havim r 2': i v i i t chains, ratchet heels other parts indi ill) I iii) thereon, the usual pattern drums, pattern catedgenera'lly at;8,.and Which, being characteristic of the said [Banner m achines, need not be described in detail.

1 Y'The machine is provided with sinkers or weld holders any suita Kletyp'e in order to support'and operate thesarnefl providen s nlrerlcain r nging desirably of usual char-am ter, surroundingv sinkers "or Web holders of any suitableitype and mounted. for radial movement in the upperedge ol 'the'needle cylmder. These sinlgers or web holders 1 are I adapted to be moved radially by means of cams of anyl suitable eharaeter. 5 The said sinker cam ringrests loosely upon or about the upper end of the needle cylinder and is id from rotation with the needle cylinder and its needles sinlrers or web holders in any suitable manner, as, for example, by

5 m ans of adjustable screws or stops tapped into ears or lugs carried by or formed upon 7 the cam ring. The said ears or lugs are spaced apart somewhat more widely than the width of the post 10 upstanding from the table. 2 and having pivoted thereon at 11 the latch or guard ring 12, whereby a certain it of lost motion is permitted between the needle cylinder and the sinker cam ring so as to per i it the proper positioning of the cams of the sinker cam ring witli' respect'to the knitting wave of the knitting needles in a manner not herein necessary more fully to c. scribe.

1 provide a suitable number of'i'ndependently operated pivoted yarn fingers of the general character shown in the patent to J oshua- DKl-Eemphili, No. 93%,969, the said yarn fingers including one for the leg of the stocking; another for thehigh splice and for the reenforceinent of' the foot, and another for the heel and toe; l he said yarn lingers are independently operated from cams upon the camshaft 7 acteristicof the said Banner machines, with the exception of the high splice" and sole reenforcing yarn finger, which I have indi-' cated at 13, in the several figures, and which i in addition to its lowest or operative position an intermediate position which it occupies when inactive during about one half course in each. of thecourses of the high splice or of position. atall times excepting during the.

formation of the high splice and the foot, and is permitted to drop into its lowest or func tioning position during the formation of the llgh splice and the foot, byth e proper p0- :itioning of the lever 15 from the said cam upon the-can 'drum. In 'order to place the said nigh splice yarn finger 13 in the" said ire liate position, namely, that occupied the course of a series of courses in the forma a rock shaft 21 mounted in theframing and manner Chalk and its highest orinoperative position, has

.Whilc inactiveduring substantiallyone half tion of the high splice and foot, I provide arm on the said'rock shaft is a rod 23 which i is connected to said lever 15 at 23, so that apart from and independently of the means for lifting the high splice yarn finger into its uppermost inactive position, the said yarn finger is'lifted into an intermediate position indicated at 13a in Fig. 4:, where the feeding end of said high splice yarn fingeris above that par ofthe lontting'wave indicated at Q h'ahd is so positioned that the reenforcing at 13c inFig. 3,- the yarn leads therefrom to the usual clamp andcutter indicated at 27 in Fig. 5. The'construction and operation of parts are such that when the high splice yarn finger occupies its highest non- "functioning position, the yarn leads thereirom above the needles to the main yarn clamp 27; when it occup es its intermediate position at 1342', the'yarn extends above the needles to-the special clamp and cutter hereinafterdescribed; and when it occupies its lowest position indicated at 13?), its yarn is benw fed to the needles.

The yarn cutter and clamp for the high .splice thread and which I have referred to as the special cutter and clamp arepreferably mounted upon the latchiring 12 and are shown in detail in Figs. 6 to 10 inclusive. The construction is such that when the latch ring is tiltedupon its pivot into inactive posit .as a part of an integral'stri'icture and are returned into functioning position with the movement of the latch ring or support into its functioning position. The said cutter and clamp, howeveryhave a movement of their own into and out of functioning position, being lowered into functioning position by means hereinafter described and elevated into non-functioning position. The saidcutter andclainp'are held in their elevated or non-functioning.position with the latch ring down at all times excepting during the formation ofthe highfs'pli'ce an'd'the foot,'and during the formation of said parts of the stocking, thecutter and clamp are held in their lower or. active position,-and while so held in theirlower or: active position-are operated twice during each' rotation-of the needle cylinder; once'to open to receive and cut the highsplice yarn at the end of the partial course [where it is knitted ll'ltO bllfi fabric, and again'to release the, yarn from the clamp, so that it may be "reintroduced to the needles attbe commencement of theueirt partial course or 1110013130121171011 of knitting tion, the cutter and clamp aremoved with into the fabric. The construction and operation are such that no yarn is lost, since floating yarns are not formed, but the hi hsplice yarn is introduced only'for the desired length of the high splice or the sole reenforcement and remains intact from the point where it is cut off to the source of supply. I

In order to accomplish the described result, I provide the following mechanism disclosed as one example-only of my invention and to which therefore the invention is not limited.

Upon the upper edge of the latch ring 12 I secure the member 28 herein shown as right angled and secured by bolts or screw-s29 said member constituting a part of a housing carried' by the latch ring, the other part of the housing consisting of the member 30 secured thereto by bolts or screws 31, and receiving between them, and guiding in its movement a slide 32 having a laterally-extending pin 32a, to which is connected a coil spring 326 secured to a spring 320 upon the member 28, the construction being such that the slide 32- remains in its lowermost position except when positively lifted. The member 30 is cut away or recessed. as indicated most clearly in Fig; .7, so as-to receive'the slide 32 and the part rigidly attachedthereto consisting of a right angledniember or piece 33 secured to the'slide at 34.- and having a head 35 extending substantially vertically downward as indicated, clearly in Fig. 7. The said head 35 cooperates with both the clamp and thecuttenwhich are both vertically movable therewith into elevated or inactive position and into lowered or active position, being pivoted thereto by a bolt 36 having nut 37 and also a coiled spring 38 to maintain the cutter 39 and the clamp 40 in cutting and clamping relation to'the opposite faces of the said head'35.

I In order to elevatethe slide 32 with the attached parts into inactive position. and to' hold the said parts in inactive position atall times except during the formation of the high splice and the sole, I preferably provide the tollowin g mechanism. I

The pivot for the yarn guide is extended as indicated at 41 andcarries hubs or sleeves .2, 43 constituting the pivot of a lever a4.

"pivotally. connected at 1 9, the said rod e7 liavii: coniiected thereto a collar 50 to which is attachedia coil s ring 51 connected at its I outer end to a pii152-upon the rrarning, wh hy the toe or end 53 or" the lever 58 1s pivotedat; 54; upon the framing, 1s

The opposite end. 46. of the.

intermediate position shown at the held upon the periphery of a cam disk 55 fast upon the cam shaft 7. The said disk 55 is provided with certain peripheral cainsindicated in their approximate posltions at 56.

57, the former cam holding the toe 53 of the j the formation oi the foot the said toe rests in the depression ne construction is such that during the forn'iation of the high splice and the sole the special cutter and clamp'occupy the position shown in Figs. 6, 7., 8 and 9. Atother times the said special cutter and clamp areelevated so that they are entirely out of the way of the other parts of the mechanism, r

in order to operate the cutter 39 and the clamp or hinder 4:0, 1 provide any suitable mechanism, but preferably the following. T he member or piece is longitudinally recessed at one face asindicated at in Fig. 8. to receive a horizontally sliding member 61 shown most clearly in Figs. 6, 8 and 10, and having at its orend a laterally extending pin 62 adaptedto be engaged pcriodicallyby the face 63 of a lever 64 pivoted at 6511- a bracket 65a extending from the post 10 and havin a bentlower end 66 extending beneath the lower part of thesinlrer cam ring bed 67,- p

' 617-40 is'opened to receive tile yarn and the cutter 39 is opened to cut the yarn, anclwhen the lever end 66 engages the cam 69, the clamp or hinder 4:0 is opened. to release the yarn to permit its reintroductionto the needles for the half course or such other partial course as is requisite for the reenforcement of the high splice and the sole of the foot.

An important feature of my invention re sidesin the formation of the clamp or binder and its position relative to the cutter. 'Viewing Fig. 9, it will be ev dent that the hinder or clamp has a substantiallyu'ight angled open. recess TO, wherein the yarnis received for clampingor binding and that the wall or face 71 of such r to the right viewing Fig-9., of the edge T2 of cutter. the wall or face 71 and the edge T2 being separated from each otherby the thickness ot the stationary head .35.

in actual constriliction, the said Wall or face ?1 advance'or" the cutting edge 72 about ee thirty-seconds the high splice yarn finger is lifted into its a the high splice yarn is first received in ess is in advanceithat is,
